Cameron Monaghan plays the villainous character The Joker while filming scenes for the upcoming season of Gotham on Wednesday (July 8) in New York City.

The 21-year-old actor is playing Jerome, a young version of The Joker in the Batman-prequel series.

Cameron‘s co-star Ben McKenzie was seen on set the day before while filming scenes and he was covered in fake blood! See the pictures in the gallery below.

A few months ago, Cameron talked about how he found the laugh for his character Jerome, who later turns into The Joker.

“I’m surprised my neighbors didn’t call the cops on me because I spent those weeks constantly laughing and staring at myself in the mirror,” Cameron told Comic Book Resources. “Even if I was driving in my car to get food or something, I was repeating the monologue. I allowed myself to be a crazy person.”

We are super pumped for tonight’s all-new Gotham, especially because Clare Foley makes her triumphant return!

The young actress stars as Ivy Pepper, who after being adopted, runs into Bruce (David Mazouz) and Selina (Camren Bicondova) while they evade the assassins chasing them.

We caught up with Clare to get the scoop on how she got the role, her favorite parts of the job, and more. Check it:

Gotham airs TONIGHT, November 24 @ 8PM on Fox!

JustJaredJr: Tell us about how you landed the role and the day you found out you got it!

Clare Foley: I auditioned for Gotham, but I didn’t know I would be playing Poison Ivy. The script was confidential and I just had to go with the sides they gave me with a fake name. I remember it was a Monday when I found out I booked the role. I was doing my homework and my mom was out with one of my brothers. She called and told me I got the part and that it was to play the young Poison Ivy. I was so excited!

JJJ: How much did you know about Poison Ivy and how much did you research?

CF: I knew about Poison Ivy from watching a bunch of different Batman movies and cartoons with my four brothers…my youngest brother loves anything Batman and has a bunch of the Lego Batman sets including one with Poison Ivy. After I found out I got the role, I watched some of the movies and shows again. I also read the very first comic Poison Ivy is introduced in.
